Police said they started their investigation after a former teacher of Austin's reported the threatening post to police.

The Facebook post mentioned a current student at school and said, "Guess what? Ima bomb mustang high school on Monday morning. No one should have to put up with the low life bigots that inhabit that school. So if you wana lose you're life keep picking on the homosexuals of mustang," police said.

Detective Michael Adams said the arrest was made just hours after the threat was reported.

"It appears that she was coming to the defense of this juvenile," Adams said.

Austin admitted to officers that she was responsible for posting the treat, police said.

"According to the suspect, she did say that she made the threat," Adams said. "She admitted to that, but she never had a bomb. She didn't have the means to make a bomb."

Regardless, police said they encourage anybody who may see or hear a threat to report it to police immediately.

"The safety of the children is of the utmost importance to us and anything, any kind of threat like this is taken seriously and not looked at as just someone blowing off steam or a joke," Adams said.

"Last week, we received information that a post had been made on Facebook by a former student of an OKC area HS - not Mustang - that inferred she was going to blow up Mustang HS,” Sean McDaniel, superintendent of Mustang Schools, said in a statement. “The post provided her name and law enforcement contacted her immediately. We continued to communicate with local police department officials and, working with them, it was determined that there was no threat to the safety and welfare of our students and staff.”
